Faxing with VoIP, Can I do it?
Faxing with VoIP can be slightly different than the traditional
Public Switched Telephone Network (PSTN). Not all VoIP providers
offer Fax capabilities and some charge extra for this feature.
Some VoIP adapters or ATA's as they are called allow fax
capabilities by simply connecting your fax to the device. If
your ATA supports fax capabilities you should not need a second
line to send faxes. Beware that unusual amounts of faxing can
violate your Terms of Service agreement with some providers and
force you to upgrade to their business service, I think the
normal user should not have a problem with this. Some providers
require you to purchase a second number for your faxing needs
and charge a minimal amount for that service usually around $5
or $10 per month.
